Bristlenose Help.

hi, how old do BN's have to be before i can sex them? i have one and its about 5cm from head to tail and has no bristles yet. does this make it definately a female? is it old enough to be developing bristles if it was a male?

By 5cm mine are usually just sprouting some bristles if you look real close. I have one though which could be around 7cm when it started to bristle up.
